I suspect that the stick position is pretty constant, but clearly the rate at which the pitch change occurred would be greater at higher airspeed. Any aeroplane could be made 'unstallable' by limiting the aft stick travel and hence elevator movement (e.g. the Ercoupe)Not sure if the trim would make a diff as it just helps relieve the control surface force. Anyway 3QDM, hurry up and strap the thing on, we're all itching to find out whether it works or not. And then we can maybe construct our own homebuilt versions by nicking the design.....
